Inkjet recording media for producing high quality images using color printers are provided. The media comprise a substrate material, such as a paper, coated with an ink-receptive composition comprising an aqueous dispersion of cationic fumed silica particles and cationic polyurethane resin. The dispersion comprises at least 60% by weight of cationic fumed silica particles, and at least 14% by weight of cationic polyurethane resin based on solids. The coated ink-receptive layer is free of surface defects and has good ink-absorption properties. The invention also includes ink-jet recording media comprising a substrate coated with an ink-receptive underlayer and an ink-receptive top layer. The resulting media may have a semi-glossy surface finish. The surface gloss may be enhanced further by calendering the coated layer.
An aqueous coating composition for making an ink-jet recording medium, comprising a dispersion of:
An ink-jet recording medium, comprising a substrate coated with an ink-receptive layer comprising:
An ink-jet recording medium, comprising a substrate coated with a) an ink-receptive underlayer comprising a pigment and a polymer selected from the group consisting of a water-soluble and water dispersible polymer and b) an ink-receptive top layer comprising:
A method of making an ink-jet recording medium, comprising the steps of a) coating a substrate with an ink-receptive underlayer comprising a pigment and polymer selected from the group consisting of water-soluble and water-dispersible polymers, and drying the underlayer;
